摘 要：
研究了小蒿草 (Kobresiapygmaea)和矮蒿草 (K .humilis)高寒草甸退化过程中植被组成、群落综合特征的变化规律 ,探讨了退化演替的物种替代机制及恢复演替模式。结果表明 ,在退化演替过程中群落主要种的优势地位发生明显的替代变化。植被覆盖度、地上生物量、优良牧草产量比例随草地退化程度的加剧而明显下降。为使退化草地向原生植被恢复演替 ,应在不同程度退化草地采取不同治理措施

摘 要：
The dynamic changes of the species component,their community roles and synthetic characteristics of kobregia pygmaeaWTBZ and k.humilisa alpine meadow in the degradation succession process were analyzed.Mechanisms of speuies replacement and models of succession were also explored.The results showed:Throughout the degradation succession process,changes in the dominant plant population were obvious.vegetatioq cover,aboveground biomass,percentage of high-quality herbage tend to decrease as the degradation succession proceeds.Different measures are adopted in different degraded grassland for vegetation recovery succession.
